Locales

In the config.yml-file you can set the Locale to be used by Bolt. A locale is
a set of parameters that defines the used language, country and any special
variant preferences that are used in Bolt's frontend.

Currently, the locale settings are only used for date formatting on the
Frontend and Backend of your site, but we're looking into adding localization
features for other parts of the Frontend and the Backend as well.

The Locale setting is defined in the config.yml-file like this:

locale: en_GB

As you can see, the locale consists of two parts: The language part, and the
country part. In some cases the codes are the same, like nl_NL for
Dutch/Netherlands. In other cases they are different, like en_US for
English/United States. Which values are supported depends on your server
settings, so you might have to try which setting works best for you. Some
common options are:

Bolt's localedatetime() function and filter uses the setting from config.yml to
set the language for the date formatting. For an overview of the options, see
php.net's strftime page, and the documentation
section on localedatetime().
